AQ6375 OPTISCHER SPEKTRUMANALYSATOR

High Performance LONG WAVELENGTH
The AQ6375 is the first bench-top optical spectrum analyzer covering the long wavelengths over 2 μm.
It is designed for researchers and engineers who have been struggling with inadequate test equipment to measure in these long wavelength ranges. The AQ6375 achieves high speed measurements with high accuracy, resolution and sensitivity, even while providing full analysis features. Troublesome calibration steps and the development of external analysis software is no longer required.

Long Wavelength 1200 nm to 2400 nm
The AQ6375 covers not only telecommunication wavelengths, but also the long wavelength region which is used for environmental sensing, medical, and industrial material applications.
High Sensitivity +20 dBm to -70 dBm
The AQ6375 can measure optical power as low as -70 dBm, which enables measurements of low power sources or low power output of a device under test.Measurement sensitivity can be chosen from seven categories according to test applications and measurement speed requirements.

High Resolution & Wide Dynamic Range
The AQ6375 uses a double-pass monochromator structure to achieve high wavelength resolution (0.05 nm) and wide close-in dynamic range (55 dB). Thus, closely allocated signals and noise can be separately measured.

High speed Measurement
GREATER EFFICIENCY
With a proprietary sweep technique the AQ6375 achieves a much faster sweep speed than conventional measurement systems which use a monochromator. Max. sweep time is only 0.5 sec. in 100 nm span.
Fast Command Processing and Data Transfer
Applying a fast microprocessor, the AQ6375 achieves very fast command processing speed and Ethernet provides up to 100 times faster data transfer speed than the GP-IB.

Free-Space Optical Input
SUPPORT MULTIMODE FIBER
Applicable fiber: SMF and MMF
The AQ6375 uses a free space input structure, not having an optical fiber inside the monochromator, that can handle both single mode and multimode fibers. The free space input is also beneficial for measurement repeatability.

Built-in Calibrator
EASY CALIBRATION
Wavelength Calibration
Calibrates with the designate absorption line of Acetylene gas.Optical Alignment Adjustment
Corrects mechanical movements inside the monochromator caused by shock and vibration.
Note: the wavelength can also be calibrated with an external light source.
Functions
Building Automated Test Systems
REMOTE OPERATIONThe AQ6375 is equipped with GP-IB, RS-232, and Ethernet (10/100Base-T) interfaces to be connected with an external PC for remote access and building an automated test system. Macro Program is a useful built-in function for making a simple auto test program.
COMPATIBLE WITH SCPI
The standard remote commands of the AQ6375 are compatible with SCPI, which is an ASCII text based standard code and format that conforms to IEEE- 488.2.
| AQ6317 EMULATION MODE The AQ6375 supports private remote programming codes of Yokogawa's best selling AQ6317 series for users to easily upgrade from their current automated test environment. (Note. some commands may not be compatible due to changes in specifications and functions.) MACRO PROGRAMMING Macro programming enables user to easily create test procedures by recording the user's actual key strokes and parameter selections. An external PC is not required because the macro program can also control external equipment through the remote interfaces. |
